ARM is the present, RISC-V is the future and Intel is the past. The magic of Apple's M1 comes from the engineers who worked on the CPU implementation and the TSMC process. The architecture has some impact on performance but I think it is simplicity and and ease of implementation that factors most into how well it can perform (as per the RISC idea). In that sense Intel lags for small, fast and efficient processors because their legacy architecture pays a penalty for decoding and translation (into simpler ops) overhead. Eventually designs will abandon ARM for RISC-V for similar reasons as well as financial ones. Really, today it's a question of who has the best implementation of any given architecture.
